PROCESS FOR MANUFAGTUBING FANCY WEBB HAVING RAISED DESIGNS.

No Drawing.

To all whom it may concern:

- Be it known that I, EDUARD Zmonsn, residing at Guntramsdorf, in Austria, have invented certain new and useful Improvements in Processes for Manufacturi'n Fancy \Vebs Having Raised Designs, of w ich the following is a specification. i

The method for producing raised designs on cotton-webs which are capable of bein napped by protecting certain portions 0 the Webs by a size impressed into the web is already known. The purpose of this is to prevent a napping along the sized portions of the web and, on the other hand to cause a fancy teasled surface to be formed along those portions of the web not covered by the size.

- By these means there will result a thick and heavy web, ornamented at the desired intervals, with raised designs, regard being had to the fact that only a-web can be employed which, by reason of its napped, rough shot, 'will permit of a raised surface being obtained. y i- Experiments haveshown that a web spot ted-withraised designs will be obtained in a technically simple and economically vantageous manner, by impressin a size on webs consisting of a mixture 0 vegetable and animal fibers; this size not only preventing the napping of web at the impressed portions of the same but, at the same time permitting the destruction or detachin of the one of the two kinds of fibers a o mentioned, whereby a raised or na ped surface will be formed.- The result 0 this will r the course of the subsequent o eration will cause acid to be'formed, or w, ichfwill detech or destroy the vegetable fiber is impressed on a web composed partially of e table and partially of animalfibers e said size will, on the one hand, prevent the napping ofthe web and, .on the other hand, will effect or cause the destruction of the vegetable fiber. By these, means the animal fiber will remain at the unnappe Specification of Letters intent.

Application flied larch 8, 1815. Serial No. 12,937.

' is sti 1 intact durin portions on which the size has been impressed, while on the non-impressed portions both fibers willbe relained and the web will be raised or napped in spots.

2. An alkaline size, or such as will be capable of detaching the animal fiber, is impressed on a web consistin partly of ani mal and partly of ve etable bers. By-these means the animal ber will be destroyed along the impressed portions of the web, so that nothing but the vegetable fiber will remain, while simult'an :ously these portions of the web will be prevented from na pin on the other hand along; the remain er 0 the web 11. 6. along the ion-impressed portion, both'kinds of fibers, and therewith a partially'raised surface, will be retained.

The employing of a fiber-destroying size yields the possibility of creating napped designs on ground-web: which, ta en by themse ves, would be absolutely unsuitable for napping since they render the formation of a raised surface altogether impossible owing to their lack of a suit able material, while on the other hand, they'would simply tear on the raising-gig. a

The obtaining of raised designs on ground-webs of the l:ind mentioned is in so far ossible, as the whole stock of fibers the very napping-operation, whereby a raised surface Will be capable of forming itself at those portions of the web left uncovered by the size. On the contrary, along those portions ofthe web on which the size has been "impressed, this lattion or injury'of the ground-web of the'one kind of fibers by the te'asable threads of the Weft of the other kind practically hiding the former that is to say, keeping them away from the raising-gig E'mamples.

A size capable oi destroying the ve etable fiber is composed of 200 parts y weight of sulfuric acid, 66 B6. and 800 parts by weight of c'extrin-paste (2:1, z. e. 2 parts by weight f1 |r each part by weight of water).

A size capable of destroying the animal fiber consists of 600 parts by weight of soda ,1 e, 40 B.,. and 600 partsby weightof extrin'paste (2:1).

' The size" is impres sad; the article is then Patented 1191317, 1917.

"ter will not only prevent a raising or napping-.but will likewise prevent the destrucor colored.

napped', whereupon the fiber-destroying action of the size comes into operation by the article being treated at a raised temperature by, say, passing it through a Mather- Platt-eva rator, a drying-cylinder or a v furnace or carbonizing.

The aforesaid process may be carried out in some cases in'which thinner fabrics with very little pile are used in such a manner that the impressing of color capable of destroying the oneclass of fibers, respectively ing modifications the raised surface of the web, will take glazce only after the carding operation has n completed. After .the destruction or detaching of the .fiber, 'the resulting waste is removed by washin ,in which case (it being the animal fiber w ich has been destroyed) a suitable substances (say, dextrin, glucose, glycerin,

or gelatin) are added to the wash-waters to prevent an injurious efi'ect of the dissociating lye in the remaining portions of the animal-fiber.

The subsequent expansion of the improved process with the .view to obtaining colored effects or desi will permit of the follow- 1. The addition of dye-stuffs and means for fixing the same to the fiber-destro irgg size whereby the fiber retained will be y 2. The employing of colors such as, are used for. dyeing or cloth-printing ca able of fixing the dgg-stufis to only one o the twokinds of fi, rs mentioned.

. 3. A combination of the working operations set forth in 1 and 2.

4. The obtainingl of effects or desi the principle of whic consists in the act of the article being, treated in d e-baths which will render the coloring of o y the one kind of fiber possible while the other 'fiber remains uncolored or but faintly colored. v

5. The obtaining ,of effects or designs the. principle of which consists in the fact of the article being treated in dye-baths com osed .of one, two or more difierent dye-stu s and' this either inone, two or more subsequent dye-baths, so that either a uniform or a dithe remaining desi veil'fing coloring of thptwo classes of fibers wi result. 6. A. combination of the working operations as set forth in'4 and 2, respectively 6 and 2. 1

What I claim is I 1. Process of manufacturing fancy webs having raised designs, consisting in covering certain places of the web with a size, capable of destroying part of the vegetable or animal fiber b maceration, and napping aces of said web for the purpose of reta ning at the impressed portions of theweb only the unnapped fiber of one kind and atthe non-impressed portions of said web, both fibers and therewith a partially covered surface of thin fabric with little pile, substantiall as described.

2. Process of manu acturing fancy webs of thin fabrics with little pile and having raised designs, consisting in covering certain yestufi' or coloring solution and being ca pable of destroying one kind of fiber, vegetable or animal by maceration, and napping the remaining places of the said web for the purtgose of retaining at the covered portions of e web only the unnapped fiber of one kind and at the non-covered portions of said web, both fibers, substantially as described.

3. Process of manufacturing fancy webs of thin fabric with little pile having raised consisting in' coverin certain places of t e web with a size, add

size'm a bath, said size being capable 0 destroying part' of the ve etable or animal ing dye stufi, fixing said dye-stuff to the fiber destro ing glaces of said web with a size containing the fiber by maceration, an finally napping the remaining places of said web for the purpose of retaining at the portions of said web covered by said size only the unnapped -fiber of one'kind and at the non-covered Egg tions both fibers, substantially as descri In testimon whereof I aflix my signature I in presence 0. two. witnesses.
